Scottish Lime Centre Trust

What Scottish Lime Centre Trust does

Scottish Lime Centre Trust (SLCT) is a Scottish-registered non-profit charity (No: SCO22692) founded in 1994 and headquartered at Charlestown Workshops in Fife, Scotland, with a secondary training facility at Merryhill Training Centre. The organization addresses a documented shortage of skills and understanding in traditional building technology, with particular focus on the appropriate use of lime mortars and the conservation of historic masonry. It operates a small multi-disciplinary team of approximately 11 staff, supplemented by contracted-in external consultants, including RICS-certified building surveyors and a PhD-holding materials analyst trained within Historic Environment Scotland's Heritage Science Team.

SLCT's core offerings span four interlocking lines: (1) practical and SQA-accredited training courses — from half-day workshops (~£90-£180+VAT) and full-day courses (£125-£365+VAT) up to five-day intensive courses (~£2,040 incl. VAT), including the Professional Development Award (PDA) in Repair and Maintenance of Traditional Masonry; (2) a Building Advisory Service providing inspection, troubleshooting, and specification consultancy to building owners, architects, surveyors, and heritage bodies; (3) a Materials Analysis laboratory offering mortar and stone analysis using petrographic, X-ray diffraction, and acid-dissolution techniques; and (4) digital and physical learning products including a DVD, four downloadable training videos, and gift vouchers. Underpinning the advisory and analysis work is what SLCT describes as the world's largest historic mortars archive (over 4,000 samples) and the UK's largest collection of currently available sands and aggregates.

The business model is hybrid: transactional course fees and advisory fees form the operating core, supplemented by recurring small grants from Historic Environment Scotland, Scottish Enterprise, and other heritage funders. Distribution is primarily direct through two physical training sites in Fife, plus onsite training at client sites, online/virtual seminars via Zoom, and e-commerce sales of digital products. Customer segments are deliberately horizontal — building contractors and craftspeople, building professionals (architects, surveyors, conservation officers), homeowners of traditional buildings, heritage organizations, and conservation students — with public-sector and heritage-body clients such as Edinburgh World Heritage, Fife Council, and Historic Environment Scotland featured in named case studies.
